I have been running our SLA5000 since April. The only two problems we
The first 2 weeks we had sporadic results, 3D replaced the beam profiler
That resolved our problems.
The 2nd, in June we had the Zephyr pump replaced. That's it!
We have not had a crash since June. This machine runs better than any
that I have used in 10 years!
As for power, we are in Florida the Lighting capital of the world. We do
not have any
special conditioned power and I have never checked the volts. Power has
been a problem, but 3D Systems is famous for blaming problems on power
with our SLA-500.
Which resin are you using?
Call me if you have any questions, I'd be glad to help.
